HANDLE-GRIP FOR CYCLE HANDLE-BARS.

To all whom it may concern:

Be it known that I, MARTIN C. SroKEs, a citizen of the United States,residing in the city of Hartford, county of Hartford, and State ofConnecticut, have invented a new and useful Improvement in Handle-Gripsfor Cycle Handle-Bars, of which the following is a specification.

This invention relates to handle grips for cycle handle bars and moreparticularly to grips for use on the handle bars of motorcycles whichare frequently driven at high speed and in which the handle bars are,con sequently, subjected to excessive vibration.

The principal object of the invention is to provide a handle grippresenting two portions; one designed for use when care in steering isrequired, and the other designed to present a grip substantially freefrom vibrations and adapted to be gripped by the rider when the steeringis easy. Minor obj ects of the invention are to provide a grip of thecharacter mentioned which is of simple design and inexpensive inconstruction, as well as of a character to afford a firm hold whengrasped by the rider.

In the accompanying drawings I haveillustrated a preferred form of theinvention, the scope of which is defined in the appended claim.

In the drawings: Figure 1 is a perspective view of a handle bar equippedwith the improved grips; Fig. 2 is a longitudinal section through one ofthe grips and the adjacent portion of the handle bar.

Referring to the drawings by the reference characters, which designatecorresponding parts in the several views, 1 designates the handle bar,which is preferably formed of steel tubing, as usual. Upon each end ofthe handle bar one of the improved grips is secured by cement orotherwise, as preferred. Each grip is designated as an entirety by thecharacter 2, and comprises a main portion 3, characterized by a largebore to receive the end of the handle bar, and an extension portion 4with a smaller bore. Both portions of the grip are preferably of largerdiameter in the middle than at the ends and are also preferablycorrugated. The material employed in the formation of the grips ispreferably rubber, which is reinforced by the insertion of fabric asindicated at 5. The main portion of each grip is rigidly held upon oneSpecification of Letters Patent.

end of the handle bar and affords a firm hold of the character requiredfor accuracy in steering wherever accurate steering is necessary.

The extension portion of each grip, being supported only indirectly bythe handle bar and being formed of a vulcanized rubber compound or othermaterial of like elasticity, is almost free from the vibrations impartedto the handle bar and, being formed with a' thick Wall, it issusceptible of a tight grasp, thus affording the rider such a degree ofcontrol over the machine as is necessary under ordinary conditions. Thethick wall of the extension portion of the improved handle grip and theabutment formed for the end of the handle bar by the reduction in thebore of the extension both contribute in an impor tant degree to thefreedom of the extension portion of the grip from the vibrations of thehandle bar. The thick wall of the extension and the consequent weight ofthe extension make it inert or sluggish in responding to vibrations.

I am aware that extension handle grips designed to afford a hand holdfree from the vibration of the handle bar have been heretofore devisedby others, the handle grips of which I am aware having been of hollowconstruction and having the extension portion formed with thin Walls andprovided with an interior coiled s ring to afford the requisite ffrmgrasp. I do not, therefore, claim broadly as my invention a handle gripfor the handle bars of cycles characterized by a resilient extensionbeyond the extremity of the bar.

I/Vhat I do claim as my inyention is:

- A handle grip for the handle bars of cycles formed of resilientmaterial and comprising a thin-walled portion having a large boreadapted to receive the end of the handle bar, a thick-walled extensionhaving a reduced bore, and a tubular fabric portion forming a lining forthe handle-receiving portion and provided with an axial extensionembedded in the thick-walled extension.

In witness whereof, I have signed my name in the presence of twowitnesses.

MARTIN o. STOKES.
